Not the best buffet in town, but definitely cheap. My most recent visit was Sunday night for prime rib dinner. It's pretty cheap especially if someone has a player's card. Our waiter was very attentive and always refilled our drinks/took our plates away. Usually isn't very crowded.
The food is not all that great though. Not a huge selection, and not the best tasting. The prime rib was nothing special. Of course, you probably shouldn't expect too much out of cheap buffets.
